Connecting To An Npn-Compatible Plc Device - Matrox Iris GT with MIL Manual

86 Appendix D: Using the I/O signals and controlled-current output of Matrox Iris GT

Connecting to an NPN-compatible PLC device

To connect your Matrox Iris GT to an NPN-compatible PLC device, connect the
ground of the NPN-compatible PLC device and the ground of your Matrox
Iris GT to a common ground. In addition, an auxiliary output signal of your
Matrox Iris GT must be connected to the device's sinking input.
The NPN-compatible PLC device provides its own power source. When the
Matrox Iris GT output signal is "on", the NPN-compatible PLC device connects
to the ground and completes the circuit.
